Richard Saner190 proved that, if a, &, a— 6 are prime to k,
a*+a*>-l'b+a*-%*+ . . . +b*sl (mod k),           <P = v(k),
since a*"*"1— 6*+1sa— 6. Changing alternate signs to minus, we have a congruence valid if a, 6 are prime to k, and if a+b is not divisible by k. If p is an odd prime olividing a=p&,
is divisible by p, but not by p2.
A. Capelli191 showed that, if a, 6 are relatively prime,
where [re] is the greatest integer ^x.
M. Bauer192 proved that, if p is an odd prime and m = p° or 2p°, every integer £ relatively prime to m satisfies the congruence
(mod m),
where A?!,. . ., /bj denote the l=<t>(m) integers <m and prune to ra>2. If m is not 4, pa or 2pa, every integer re prime to m satisfies the congruence
(&'to<*-l)2=(x+kl)...(x+kd (mod m).
L. E. Dickson193 proved Moore's181 theorem by invariantive theory.
N. Nielsen194 proved that, if \$(x) is a polynomial with integral coefficients not having a common factor > 1, and if for every integral value of x the value of \$(x) is divisible by the positive integer m, then
\$(z) = <Kz) 6>p(s)+ S mp_, A. wf(x),    con(oO=z(o;-j-l) . .(s+n-1), «- 1
where <#>(o;) is a polynomial with integral coefficients, the ^4.8 are integers, p is the least positive integer for which p ! is divisible by m, and mp_3 is the least positive integer I for which s!Z is divisible by m. CL Borel and Drach.180
H. S. Vandiver195 proved that, if V ranges over a complete set of incon-gruent residues modulo m = pia . . .pjfc, while U ranges over those F's which are prime to m,
modulo m, where «. = (m/p*»)e, e =</>(p/0 .    For m = pa, the second congruence is due to Bauer.186- m
